U.S. long-term interest rates are rising rapidly, signaling new risks to the market. Analysts note that the 30-year Treasury yield approaching the 5% level reflects combined pressures from heightened inflation expectations and a weakening growth outlook, which could negatively impact equities and the broader economy.

Data shows the 30-year Treasury yield briefly climbed close to 4.98%, nearing the psychologically significant 5% mark. This rate serves as a key benchmark for long-term financing costs and is widely viewed as a barometer of market confidence in future economic conditions.

Unlike last year, institutions point out that the current yield increase stems not from strong economic performance but rather from a repricing of inflation risks. The core driver behind rising rates appears to be the emerging stagflation environment. On one hand, international oil prices remain near $100 per barrel, elevating energy and transportation costs. On the other hand, U.S. economic growth has noticeably slowed, with revised data showing annualized GDP growth for the fourth quarter of 2025 at just 0.7%, well below prior expectations.

Under these conditions, the bond market has weakened despite the economic slowdown, indicating that inflation concerns have overtaken growth worries. Market observers highlight that when long-term rates rise due to inflation risks rather than economic expansion, the impact on stocks and consumer spending becomes more pronounced. Higher interest rates not only increase corporate borrowing costs but also directly raise mortgage and auto loan burdens for households, thereby suppressing consumer demand.

Concurrently, a "full curve sell-off" has emerged in the bond market, with yields rising broadly from short-term to long-term Treasuries, suggesting a market-wide reassessment of the inflation trajectory. Analysis indicates that oil price shocks are gradually transmitting through diesel, fertilizer, food, and transportation costs, which may ultimately push core inflation higher.

In this environment, concerns are growing that the Federal Reserve may alter its policy path. If inflation remains persistently high, monetary policy could be forced to maintain tight conditions or even return to rate hikes, further increasing downside risks to the economy. Some strategists warn that under a "high inflation, low growth" scenario, the U.S. economy faces the possibility of recession.

In equity markets, although overall performance has remained resilient since the onset of recent conflicts, major indices have retreated significantly from historical highs and are approaching technical correction territory. Internal market volatility has intensified, with investors remaining highly alert to energy shocks, rising rates, and economic uncertainty.

Additionally, several institutions note that even if geopolitical tensions eventually ease, energy prices are unlikely to quickly return to pre-conflict levels, suggesting the global economy may enter a "higher cost" new normal. This implies inflation pressures could exhibit greater persistence, further testing central banks' ability to balance growth and price stability.
